Problem with flashforge compatibility

i have a flashforge dual head modified, i have instal a bowden system with gear head

i have start to print with your software but i have some strange thing

firstly, the speed unit are very very hight, for a normal speed in reality

secondly, the tool path is really not good , if i calibrate the good flowrate for have 0.4mm thickness in vase mode, when i print the solid base, my flowrate is really under extrusion, the the path look like for a nozzle 0.8mm and not 0.4mm
